Apparatus and method for generating dynamic response

A dynamic response generating apparatus, the apparatus comprising:

• a controller to control an operation of the dynamic generating apparatus;
• an information receiving unit to receive user input information from an inputting device;
• an analyzing unit to analyze an intention of a user based on the user input information;
• a first response generating unit to generate first response information associated with the analyzed intention of the user;
• a modality determining unit to dynamically determine a modality with respect to the first response information by analyzing at least one of the first response information, context information associated with the user input information, user motion information, and environmental information;
• a second response generating unit to dynamically generate second response information in a form of the determined modality by processing the first response information;
• and
• an outputting unit to output the second response information and a content in the form of the determined modality.
